POWER-LOOM FOR WEAVING WIRE-CLOTH.

SPECIFICATION forming part of Letters Patent No. 235,371, dated December 14, 1880.

Application filed June 25, 1880. (No model.)

To all whomjt may concern Be it known that I, THOMAS MoOLUsKY, of Belleville, in the county of Essex and State of New Jersey, have invented a new and useful Improvement indower-Looms for Weaving Wire-Cloth, of which the following is a specification. 7

My invention relates to an improvement in a power-looms for weav pg wire-cloth; and it consists in the combination, with the lay, of two or more vibrating arms actuated by the connecting-rods usually employed to move the lay, and pivoted dogsnnpon thecross-beam of the lay, to engage withthe ends of the vibrating arms.

It also consists in the combination, with an automatic let-off applied to the warp-roll, of a gravity take-up consisting of a drum, cord, and weight applied to the cloth-roll.

The entire purpose of my invention is to beat up the filling with great uniformity, and this I accomplish by the use of a suspended lay acting upon the weft by the force of gravity, the vibrating arms employed to actuate the same affording special facility for adjusting the force of the blow to the size of the wire and the mesh, and the positive let-off mechanism serving to keep the face of the work always in one place to insure uniformity in the blow of the reed. v

In the drawings annexed, Figure l is a sectional elevation of a loom on line a: a; in Fig. 4. Fig. l shows a section of the cross-beam of the layandone of the pivoted dogs carried thereby." Fig. 2 is a detached view of the connection between the shedding-treadle and the let-off ratchet-wheel. Fig. 3 is a plan of one end of the loom, the heddle-frames and various other parts being removed to show more plainly the cam-shaft J its connection with crank-shaft e WhTKJhe let-off mechanism, and the cloth-roll 1), with its take-up drum and cord 0. Fig. 5 is aplan of the adjustable box b Fig. 6, a side view of the same and the box a; Fig. 7, a bottom view of the box at; Fig. 8, a side view of the means of adjustment of the devices for operating lever q, and Fig. 9 an edge view of the same.

A A is the frame of the loom; B, the lay,

suspended by its swords 0 upon pivots 1), arranged in boxes b upon the top of the frame.

D is the cloth-roll; E, the warp-beam; F, the breast-beam; G, a cross-bar inserted between the swords abox e the reed r, and H the vibrating arms employed to operate the lay in lieu of the usual positive crank-connections.

The arms H are hinged by their upper extremities to a fulcrum-bar, f, supported in adjustable boxes it upon the frame beneath and in front of the pivots p.

Spring-dogs d are secured to the cross-bar G in such a position that when the lay hangs vertically the lower ends of the vibrating arms will catch them in their backward movement and pull the lay back the required distance. The fulcrum-bar f is, however, so located in reference to the pivots of the lay that the ends of the vibrating arms slip off of the dogs (1 at any predetermined point, which is adjusted by means of steel toes i, fastened adjustably to the lower ends of the arms H by bolts. This slipping of the toes 45 off from the dogs (I is caused by the different arcs in which they swing, as shown at a and a in Fig. 1.

The farther the toes project below the ends of the arms H the longer the dogs 0! will be pulled backward, and the farther the lay will swing before striking the face of the work, and the harder the weft will be driven into the warp.

The crank-shaft e is mounted upon uprights in the frame A, its center being placed higher than the front ends of the connecting-rods c, which are thus greatly inclined when pushing the arms H forward,and consequently produce a more rapid motion of the arms in that direction than when they are drawn backward and the connections are in a nearly-level position. The arms thus operate effectively to pick up the lay upon its rebound after the blow upon the filling. To permit the toes t to pass over the dogs 01 at this time, the dogs are hinged at their rear ends low enough for the toes to pass freely over them, and the front ends are raised up to engage with the toes by springs s, the rear ends of the dogs being bent downward, as at d, to bear upon the rear of bar G and regulate the elevation of the front ends.

With the means described, it is evident that the stroke of the lay may be adjusted exactly to the proper degree for the wire and mesh used in the cloth, as the pivots p can be ad justed in relation to the face of the work and i the fnlcrum-shaftf to the pivots p and shaft 0, while the toes? can be set in any desired po- R sition to engage with the dogs (I. In addition to this, the use of the vibrating arms affords a most convenient means of producing a double blow upon the weft in each stroke of the shuttles. To effect this I provide two sets of arms, as shown in Fig. 4, and operate two of them to draw back the lay for one blow and two for the other blow, both sets of arms being operated by connecting-rods c d urin g a single revolution of the crankshaft c and a single shot of the fillmg.

The let-ofl'devicc is operated as follows: The warp-roll E has its shaft provided with a wormwheel, M, at one end, operated by a worm, L, secured to a shaft, N. A ratchet-wheel, It, is also secured to-the worm-shaft N, and is turned one or more teeth at each stroke of the trcadles m bya connection, y, operating a hcll-crank lever, q. carrying a pawl, I, and mounted upon shaft N beside the ratchet-wheel. The heddles (shown at It in the drawings) are operated by treadles .r, pivoted to the rear of the frame, and actuated by cams I, mounted upon a shaft, J, as is usual in powenlooms. The shaft J may be connected with the crankshaft 0 by gearing or by achain-belt, to secure uniformity of motion, a belt, K, being shown in Figs. 1 and 3. The treadles are thus operated at each stroke of the shuttle, and the let off operated to deliver the wire used ili one mesh.

The connection g may, if desired, be made adjustable to and from the fulcrum r of the treadle, and the motion thus varied to take the desired number of teeth in wheel It.

The adjustments of various parts referred to herein may he made as indicated in Figs. 5 to 9, inclusive, where the boxes b for the pivots of the lay are shown provided with slots b and bolts b, with which they may be sccured in any required position.

In like manner the boxes n for the fulcra of the vibrating arms may be formed with slots at, and secured in any required position by bolts n.

For adjusting the connection of the bellcrank lever q with the trcadlc .1, the latter may be provided with a row of holes, m, as shown in Fig. 8, and the lower end of the connection be secured to any of them at pleasure; or an auxiliary lever, i, may be provided and pivi oted upon the framing; of the machine at l, i above the treadle .r, and an auxiliary connection, 14, be employed to connect the holes at in the treadle with similar holes m in the lever l t. The connection gcan thus be permanently connected to the outer end of the lever t, and 1 thus maintained in the same position, if preferrcd.

Any equivalent means of adjustment may be employed, as the precise mode of securing;

these objects is not material to my invention.

To take up the cloth uniformly upon a clothroll gradually increasing in size, I employ a gravity-tension. I apply a drum, Q, to the shaft y of the cloth-roll D, and attach thereto a cord or chain, 0, strained by a weight, W. The cord is carried over a pulley, P, mounted upon the top of theframe A, so as to pull up ward as it leaves the drum Q; but it may be arranged in any other convenient manner.

By employing additional weights in connection with weight W the tension may he made practically uniform while the cloth-roll is gradually filling, or the tension may he materially changed at the pleasure of the opera tor.

The warp-wires are shown in the drawings at a, the opened shed at k, and the cloth at u.

Since the warp stretches sometimes five or ten per cent. in passing from the roll E to the breasbbeam 1', it is evident that any positive take-up applied to thc cloth-roll would soon disagree in its operations with the positive letofi l have described above.

The gravitytension I have devised is therefore especially useful in such a combination, as it produces a nearly uniform tension upon the cloth, and accommodates itself automate cally to the let-ofl" operated by the treadle.

Ido not considerthat either the take-up or lebofl' would operate satisfactorily alone, and therefore claim them herein as necessary to one another.

I have shown an adjustable spring", S, attached to the topof the swords, and regulated by a screw and nut to increase or diminish the effect of gravity upon the lay. I am, however, aware that such a device has been used before, as well as other means for operating, a suspended lay by the force of gravity.

I therefore claim only the specific devices I have shown in the following manner:

1. In combination with the lay provided with dogs d, for the purpose specified, the vibrating arms H, the connections 0, and crankshaft 0, all constructed and operated substantially as shown and described.

2. The combination of the cloth-roll I) and its drmn, cord, and weight with the warp-roll E, worm-wheel M, worm L, shaft N, ratchetwheel It, pawl l, lever q, the loom-treadle devices for connecting said lever and trcadle, and means for operating the treadle, substantinlly as described.
